I finally got around to listening to this and I have to say I'm disappointed. The direction they went with all the English vocals definitely isn't what I was looking for, and the even the instrumental tracks aren't anything particularly special. The mastering/production also isn't particularly great, but that's another story.
I would encourage you to give it subsequent listens. Things that I totally missed on initial listens that have caught on since, and have also made me fall in love with the album:
1) concept album about Schala and Kidd and ... their relationship as being the same person, and not. Every song chosen has some strong connection to one or both characters (Wind Scene and Marbule are iffy, but close enough). Consider the English lyrics for Corridors of Time (tr8, Shigihara vocals) ... a song from Schala's perspective of her little brother's warnings that crap is about to happen, that she would run if her mother wasn't a psycho that held her prisoner ... and then at the end, "was my life just taken from me?" -- the moment she uses the last of her powers to teleport everyone to safety, the moment she merges with Lavos, the dimension rift forms, everything... All in that moment.
2) Star-Stealing Girl was snuck in. When I initially saw the tracklist I was deeply saddened that this lovely, simple piece of music (which fit the theme perfectly) was missing. But it's *not*. It's just embedded as an instrumental solo in track4 (more Shigihara, Schala's theme, pseudo-language stuff). After 2nd chorus, you get that beautiful melody, and on a real Celtic pipe that sounds far better than the CC OST "la-la" vocal synth.
3) "Marbule" is the instrumental track that all the vocal-haters can focus on. It's 100% on-par with Xenogears CREID's instrumental tracks (esp tr. 3 and 5, Balto and Dajil). For the people who couldn't swallow the vocals, I could understand wishing the album had been 10 tracks of THIS. I would've dug that too. An all CC album that wasn't themed around Schala could do just that. What can we do to motivate Mitsuda to put out YET ANOTHER arranged album? Because whatever we can do, I'm in.
4) Kumi Tanioka on piano. She plays piano on the Sarah Allain tracks (2 and 10), and her piano work is just ... it's stupidly-good. I had the pleasure of seeing Tanioka-san perform some FFXI tracks, solo on a weighted keyboard, at FF Fanfest 2008. It was a great little intimate showing of her talents. But give her a baby-grand in a studio with infinite takes, and ... wow. She is QUITE the pianist!
I can understand being disappointed since this album isn't at all what many people wanted. But if you're willing to accept it on its terms as concept album ... well, I think it's more than "just okay." I can't think of a singularly more cohesive arranged album from Square Enix than this. And considering my love for ... well ... most other SE arranged albums, especially some of the great old stuff (Seiken Densetsu orchestral, here's lookin' at you!), I think that's saying something.
